Nap-50a is a miniature & low power consumption type sensor. Nap-50a is
Mainly used for gas detectors. Compared to nap-55a, nap-50a has a lower
Alcohol sensitivity to eliminate false alarms caused by alcohol, thus more reliable
Gas detectors can be produced with nap-50a. The following are the basic
Characteristics but it is recommended to refer to the individual user’s manual for
Further information. See nap-66a for measuring circuit for sensor evaluation.

NAP-57A Catalytic Type Gas Sensor Description
NAP-57A is a newly developed catalytic type gas sensor based on conventional type NAP-56A for not only residential but also commercial or semi-industrial applications because of having highly excellent poisoning resistivity. Since its power consumption and pin positions are completely the same as NAP-55A and 56A, it is easily replaceable as it is. However, it does not possess the explosion proof by itself, then it is recommended to install it into an explosion proof chamber for actual application.

* Good stability
* Excellent repeatability and detection accuracy
* Good linearity against gas concentration at wide range
* Quite excellent poisoning resistivity
* Down sizing for design flexibility of gas alarm or detector

Cirius1 Infrared Sensor for Hydrocarbons Description and Operation
The Cirius range of sensors use the non-dispersive infrared method to detect the presence of gases. The sensors contain an infrared radiation source, a dual element infrared detector and a patented optical arrangement into which gas diffuses. The dual element infrared detector responds to changes in incident radiation and to operate he sensor the infrared source should be pulsed with a duty cycle of 50% at a frequency typically between 2Hz and 4Hz. The sensor produces outputs for active wavelengths, which are modified by the presence of target gas, and for reference wavelengths, which are not modified by the presence of target gas. These outputs consist of a small AC signal in sympathy with the source pulse that is superimposed on a DC voltage pedestal. The sensor also provides a measure of internal temperature via an embedded thermistor. The sensor requires a voltage supply to operate the infrared detector and the connections to the sensor follow the industry standard 7 pin format.
To operate the sensor it must be connected to a suitable circuit that provides the source drive and extracts the small AC signals from the DC voltage pedestal. The circuit must amplify the small AC signals, extract a value from them and treat the results to provide a linear output related to gas concentration. The temperature output from the sensor should be used to apply temperature compensation in order to achieve the full performance specification.
Cirius1 Infrared Sensor for Hydrocarbons Features
* Sensing ranges: 0-100% LFL Methane, 0-100% LFL Hydrocarbons and 0-100% volume Methane
* All metal construction
* Small internal volume
* 'Lightlocked': not affected by external illumination
* Low power
* Active and Reference signal outputs
* Embedded thermistor temperature sensor output

* Electrically isolated housing
Description
The ngm2611 is a pre-calibrated module for natural gas alarms which is precisely
Calibrated in figaro's humidity and temperature controlled facility.
The most important process in manufacturing reliable resdential gas alarms is
Adjusting the alarm point. Calibration is a complicated and time consuming
Process which also requires a substantial investment in calibration equipment. By
Eliminating the costly calibration process, this module enables users to easily and
Simply manufacture residential natural gas alarms. Figaro has taken the complexity
Out of designing a gas detector circuit by providing users with a temperature
Compensation circuit which combines a built-in thermistor and individually adjusted
Load resistor together with figaro’s low power methane gas sensor.
A connector allows easy replacement of the module for the purpose of periodic
Sensor renewal. This input/output connector enables easy installation of the
Module into the gas detectors’ mother board. This same mother board can be
Used for both methane and lpg gas detectors by simply changing the module.
This module is designed to meet the performance requirements of en50194, and ul1484.
Please refer to “technical information for tgs2611” for sensor sensitivity characteristics.
Refer to “application notes for tgs2611” for further information regarding circuit design.
